Study Notes
Foreground vs. Background Questions
- Foreground questions are specific and aim to identify the effect of a particular intervention.
- Background questions are general and provide broad knowledge about a topic.
- Foreground questions utilize the P.I.C.O. framework (Patient, Intervention, Comparison, Outcome) for precision.
- Background questions involve inquiries like who, what, where, when, and how.
The PICO Process
- PICO helps clarify the single most important issue from the patient's perspective.
- It assists in defining language and key terms for online searches.
- PICO focuses on identifying specific problems and expected outcomes.
- Helps determine the types of evidence needed for effective interventions.
Qualitative/Descriptive Primary Research
- Qualitative research complements quantitative research by providing context and understanding the underlying reasons.
- Ethnography examines group cultures through observation and interviews.
- Phenomenology focuses on personal experiences via in-depth interviews, anecdotes, and artistic expressions.
- Grounded theory emphasizes theory development from natural interactions.
Potential Biases in Clinical Research
- Recall bias: Impacts self-reported data accuracy, common in retrospective studies.
- Selection bias: Occurs in non-randomized group assignments, affecting observational study validity.
- Investigator bias: Researchers' influences can skew outcomes in qualitative designs.
- Placebo bias: Participants’ perceptions of treatment effects can alter study results.
Role of the Researcher
- In quantitative research, the researcher remains detached from the subject.
- In qualitative research, the researcher is deeply involved and interacts with the subject matter.
Quantitative/Analytical Secondary Research
- Secondary research primarily comprises synthesized publications of primary research.
- Systematic reviews and meta-analyses summarize findings from multiple studies on specific questions.
- Over 2 million articles are published annually, making systematic reviews essential for information synthesis.
Systematic Reviews vs. Traditional Narrative Reviews
- Systematic reviews have a narrow focus on specific patient problems and pre-established inclusion criteria.
- Traditional narrative reviews have a broader scope and may lack strict criteria.
- Systematic reviews minimize bias and report findings in a structured format.
Finding Evidence: Resources
- Cochrane Database of Systematic Review offers full-text systematic reviews and protocols.
- DARE provides abstracts of effectiveness reviews.
- The Cochrane Central Register lists controlled trials.
- CINAHL contains evidence relevant to nursing and allied health fields.
- PubMed Clinical Queries supports evidence-based search methodologies.
Boolean Operators for Searching
- AND: Narrows searches by requiring both terms.
- OR: Broadens searches by including either term.
- NOT: Excludes terms, refining search results.
- Using parentheses prioritizes information within them during searches.
Levels of Evidence
- Evidence is ranked to reduce bias and enhance reliability in patient care decisions.
- Randomized Controlled Trials (RCTs) offer stronger evidence than cohort or case-control studies.
- The "Evidence Pyramid" illustrates the hierarchy of evidence quality, with higher levels providing more reliable answers to clinical questions.
